Find the common solution to the following pair of lines, 4x + y = 1
y = x + 6, by graphing them on the same axes. Where do they intersect?

4x + y = 1 y = x + 6, substitute y in the first equation the result is 4x + x + 6 = 1 5x = -5 x = -1 y = -1 + 6 = 5 the solution for the system 4x + y = 1 y = x + 6 is (-1, 5)

4x + y = 1

y = x + 6,

substitute y in the first equation the result is

4x + x + 6 = 1

5x = -5

x = -1

y = -1 + 6 = 5

the solution for the system 4x + y = 1 y = x + 6 is (-1, 5)

y = x + 6,

substitute y in the first equation the result is

4x + x + 6 = 1

5x = -5

x = -1

y = -1 + 6 = 5

the solution for the system 4x + y = 1 y = x + 6 is (-1, 5)
